Zhe Zhang commented on HDFS-7837:
---------------------------------
Great work Jing! I haven't finished reviewing the entire patch but below is
what I have now:
# I updated title of HDFS-7339 to reflect the adjusted scope.
# Should we use {{BlockInfo#isStriped}} to replace instanceof calls in all
places?
# {{BlocksMap#removeBlock}}: why should we use capacity instead of numNodes for
striped blocks?
> Erasure Coding: allocate and persist striped blocks in NameNode
> ---------------------------------------------------------------
